The Siemens 6ES7138-4DE02-0AB0 is an ET 200SP counter module accepting 32-bit incremental encoder signals at up to 650 kHz via RS-422, with two digital outputs for response signals and zero-mark capture. Supply is 24 V DC (L+ minus 0.8 V) drawing 2 W typical. The module fits a single-width 30 mm base unit and carries diagnostics via the group-error SF red LED.
30 mm wide × 81 mm high × 52 mm deep. Shielded encoder cable max length: 1 000 m; unshielded: 600 m.
52 mm, fitting standard ET 200SP dimensions.
